Opening Files as command line arguments

Hi have set a command line argument where the user enters the filename.

I have set a condition that if the command line is null (user just enters return), the script will exit (with an error message).

However, what if the user types something and the file isn't found. How will I go about defining that condition?

Thanks

rt-crontool(1)						     Request Tracker Reference						    rt-crontool(1)

NAME
rt-crontool - Command-line interface to Request Tracker SYNOPSIS
# find all active tickets in the queue 'general' and set their priority to 99 if they are overdue: rt-crontool --search RT::Search::ActiveTicketsInQueue --search-arg general --condition RT::Condition::Overdue --action RT::Action::SetPriority --action-arg 99 --verbose # Escalate tickets rt-crontool --search RT::Search::ActiveTicketsInQueue --search-arg general --action RT::Action::EscalatePriority DESCRIPTION
This script is a tool to act on tickets from an external scheduling tool, such as cron. Security: This tool allows the user to run arbitrary perl modules from within RT. If this tool were setgid, a hostile local user could use this tool to gain administrative access to RT. It is incredibly important that nonprivileged users not be allowed to run this tool. It is suggested that you create a non-privileged unix user with the correct group membership and RT access to run this tool. OPTIONS
search Specify the search module you want to use search-arg An argument to pass to --search condition Specify the condition module you want to use condition-arg An argument to pass to --condition action Specify the action module you want to use action-arg An argument to pass to --action template Specify name or id of template(s) you want to use transaction Specify if you want to use either 'first', 'last' or 'all' transactions transaction-type Specify the comma separated list of transactions' types you want to use log Adjust LogToScreen config option verbose Output status updates to STDOUT perl v5.14.2 2013-05-22 rt-crontool(1)
